Abstract
The objective of this research is to test the control efficiency of marketing corn from Al-Latifyia region to the factory of Al-Musyab by using ststistical quality control method (P- Chart) . The tabulation of research population data was achieved . The sample observations were 94 elements. The duration was three months . It began from November (2006) to January (2007). Nine subgroups were taken every unfollowing four days . They comprised all research population elements . therefore they had unequal size .The Levene test was achieved , the result showed homoscedasticity for these subgroups . The result showed the deviations from center line of( P-Chart) were happened because of chance causes , therefore the quality of corn is under control . The necessary suggestion is to use statistical quality control charts by the corn factory of Al-Musayab because this kind of quality control is never use in this factory to determine the marketing corn which is out of statistical quality control to treat the defect in case of finding it
